A polite +1 that xpDynamics/xpShatter workflow could use more work.
1. It doesn't make sense to me that a push is needed? Is that the same as an collision? It makes the shards blow/push apart in a way that doesn't look natural.
2. The performance make it impossible for me to use it. If, in the attached scene, I turn on the Spawn Points on my xpShatter the simulation gets to slow to use.
Not 100 % sure if I'm doing something wrong or if this is simply the performance to be expected.
